Steam iron shoe

ABSTRACT

With this steam iron shoe, drier pressing can be obtained because the steam from the steam iron, passing through perforations in the shoe body, is drier. This shoe applies more heat to the moisture in the steam from the steam iron, to make the steam drier. This is accomplished by making the body of the shoe of a laminated top layer of non-ferrous metal, intermediate layer of cloth treated with high heat resisting material and a bottom layer of TFE Teflon, all similarly perforated. Also the metal layer is increased in thickness to hold more heat for drying the steam.

With this steam iron shoe, drier pressing can be obtained because the steam from the steam iron, passing through perforations in the shoe body, is drier. This shoe applies more heat to the moisture in the steam from the steam iron, to make the steam drier. This is accomplished by making the body of the shoe of a laminated top layer of non-ferrous metal, intermediate layer of cloth treated with high heat resisting material and a bottom layer of TFE Teflon, all similarly perforated.

21 Claims, 4 Drawing Figures STEAM IRON SHOE This invention relates to steam iron shoes. One object of this invention is to provide a steam iron shoe of the character described comprising a shoe bottom comprising a top layer of non-ferrous metal, an intermediate layer of cloth treated with high heat resisting material, and a bottom layer of high heat resisting material.

Another object of this invention is to provide a highly improved steam iron shoe of the character described in which the top layer is aluminum, copper, brass or other non-ferrous metal, the intermediate layer is Nomex (nylon) cloth impregnated with FEP Teflon (fluorinated ethylene polymer) and in which the bottom layer comprises TFE Teflon (tetrafluoroethylene).

Still another object of this invention is to provide a steam iron shoe of the character described in which adjacent layers are bonded with layers of PEP Teflon.

Yet another object of this invention is to provide a steam iron shoe of the character described in which the aluminum top layer is of substantially increased thickness to hold more heat for making the steam from the steam iron and passing through perforations in said layers, drier.

A further object of this invention is to provide a steam iron shoe of the character described in which three layers of the body are formed with registering or aligned perforations throughout the body.

A still further object of this invention is to provide a steam iron shoe of the character described comprising a body having a bottom flat wall shaped like the underside of a steam iron, on which the steam iron rests, upwardly extending flanges projecting up from all around the bottom wall, a frame of inverted U cross-section receiving the upper edges of the flanges and fixed thereto, and a plurality of coil tension springs the ends of which are anchored to opposite sides of the shoe, to be passed around the steam iron to resiliently hold the shoe to the iron.

Yet a further object of this invention is to provide a steam iron shoe of the character described in which the ends of the springs on each side of the shoe are anchored to the frame.

It is also an object of this invention to provide a strong, smooth and durable steam iron shoe of the character described which shall be relatively inexpensive to manufacture, easy to manipulate, light in weight, which shall produce drier steam for ironing wrinkle-less garments, which shall comprise a high tenacity composite body, which shall be easy to put on and take off the steam iron and which shall yet be practical and efficient to a high degree in use.

Other objects of this invention will in part be obvious and in part hereinafter pointed out. w

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which will be exemplified in the construction hereinafter described and of which the scope of invention will be indicated in the following claims.

IN THE DRAWINGS FIG. 1 is a top plan view of a steam iron shoe embodying the invention;

FIG. 2 is a side elevational view thereof;

FIG. 3 is a cross-sectional view taken on line 3-3 of FIG. 1; and

other non-ferrous metal, an intermediate layer of Nomex (nylon) cloth impregnated with FEP Teflon (fluorinated ethylene polymer) or other high heat resisting material, and a bottom layer 16 of TFE Teflon (tetrafluoroethylene). The lamination is accomplished by layers 17 of FEP Teflon of substantially 0.002 inch to 0.010 inch in thickness. The FEP Teflon melts at about 500F. The TFE Teflon melts at about 750F.

The bonding is accomplished at about 700F. The three layers of aluminum, FEP treated Nomex, and TFE Teflon are bonded together at one time in flat sheets which are formed with perforations 18 by punching the multilayered sheet. Then the sheet is cut to desired shape and the flanges are then upturned by a proper die or other suitable apparatus.

The flange 13 has an upper edge 20 at the same level all around. The bottom wall 12 of the shoe has the shape of the bottom surface of the steam iron, being transversely straight at the back and convergingly curbed at the sides merging in substantially a front apex.

If desired, the body may have slits where the rear flange meets the rear ends of the forwardly converging curved side flanges, and at the apex of the body, to facilitate shaping of the flanges. The aluminum or other non-ferrouslayer 14 is preferably about 0.040 inch in thickness. It may be from 0.025 inch to 0.060 inch in thickness. This is an increased thickness of aluminum. The thicker the aluminum the more heat it holds and hence the more heat it holds the greater the increase in the temperature of the steam and that is accompanied by lessening of moisture in the steam, thus, resulting in drier steam.

The TFE Teflon bottom sheet is preferably about 0.030 inch in thickness.

Heretofore steam iron shoes were made with a flat wall of metal of only 0.020 inch in thickness which is not satisfactory to produce drier steam.

The perforations 18 are closely spaced arranged in transverse, closely spaced rows. Said perforations are about 1/16 inch in diameter.

The flanges are about /2 inch in height. Mounted on the upper ends of the flanges is a frame 24 of transverse inverted U-shape forming a downwardly opening channel 25 into which the upper end portions of the flanges 13 project. The frame may be made from a single channel-shaped piece of metal bent to the shape of the flanges 13 by split at the middle of the back. The frame has a web 24a, an outer flange 24b and an inner flange 24c.'Said frame is fixed to the flanges 13 by spaced rivets 30.

The portions of the frame 24 at opposite sides of the split at the rear, are held together by a transverse downwardly opening straight channel-shaped member 35 fitted over the end portions of the frame 24 located at the back of the shoe and straddling the split or space between the ends of frame 24, and is riveted thereto by a pair of side rivets 36 and a central rivet 37'which is located between the adjacent ends of the frame 24.

Means is provided to anchor a pair of coiltension springs 40 to the shoe. To this end, portions of the web 24a at opposite sides of the frame 24, somewhat closer to the front end of the frame than to the rear end of the frame, are cut away to form holes 41. Inserted into each side of the frame is an anchor 42 of metal wire stock having longitudinal oppositely extending arms 43 located beneath the web 24a and above the upper edge of the flange l3, the-inner ends of said arms being interconnected by an upwardly extending loop 44 projecting up through hole 42. At the adjacent ends of the springs 40 are loops 40a engaging the loops Thesesprings can be pulled around parts of the steam iron in any suitable manner to resiliently press the steam iron down on the flat wall portion of the shoe and to hold the steam iron within the confines of the frame Pointer means provided to guide the steam iron and shoe forwardly. To this end a line 50 may be applied to the web 24a at the apex of the frame and running in a direction along the axis of the shoe. This line may be applied by silk-screening or in any other suitable manner, such as by a wire welded to the frame or by awire inserted intothe frame andprojecting above the frame. i It would thus be seen that there is provided a device in which the several objects of this invention are achieved and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in'the embodiment aboveset forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative.
